2: Adapter 9 pin D-sub to RJ45This is the connector that is different from the EQ6 mount. It's a telephone / internet plug, a RJ45 eight pin connector. The EQ6 mount has a 9-pol D-sub connector. I followed this instruction how to connect the cable: I had one RJ45 cable with a broken contact in one end. I can use the working end of it and connect to the EQDIRECT cable I already have but with wrong contact, the 9-pol D-sub which EQ6 mount use. First I check that the plug on the cable is mechanically correct. The network cable is a bit stiff and I cut it short. The old EQDIRECT cable I already have is an USB to 9-pol D-sub cable, this is the connector that I have to replace. On the other end it's USB terminal with built-in FTDI chip.
I open the enclosure, there are only three cables in there: According to the instructions above I should have a 12 Volt wire also, but there is no one here, I don't see what need it can be of it either. The chip must take the 5-volt power from the USB connector. The pin layout of 9-pol D-sub:
Note: Now I only have to connect cables to each other. Follow the first link and this how to connect them. RJ45 pin layout:
Note: I install a short bit of shrink tube on each wire and a big one around the whole cable. Important to not heat the shrink tube when soldering the cable. I try to protect it from heat with the crocodile clamp. Second wire soldered. The wire I don't use I keep, put a shrink tube on top of each to not make any short cut between them. The outer shrink tube shrank and the cable is finished. I bought this cable from a friend who had lot of problem with the communication over it, and another friend to me made this cable. We are not sure what caused this problem, if I also get in trouble I found this link that will be of great help: I took apart the USB contact to see what's inside. With Windows system this driver is recommended for this cable, it has the FTDI chip:
